MOLE-PLOW.

SPECIFICATION forming part of Letters Patent No. 397,682, dated. February 12, 1889.

Application tiled December I7, 1887. Renewed August 2l, l 888. Serial No. 283,370. (No model.)

To all whom it may concern;

Be it known that I, JOHN (.1. ALLEN, a citizen of the United States, residing at Brookston, in the county of White and State of Indiana, have invented certain new and useful Improvements in Mole-Flows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to devices for forniing moles or ditches for draining and other purposes; and it has for its object means for introducing cement into the trench or ditch and in rear of the cutter-toot, means for depositing the cement against the top or upper portion of the ditch, and means for keeping the discharge-throat of the mole free from clogging. l

The invention will be fully understood from the following` description and claims, when taken in connection with the accompanying drawings, in whichM Figure l is a side elevation of a mole-plow constructed according to my invention. Fig.

2 is a vertical longitudinal sectional view of l the same. Fig. 3 is a sectional view taken on the lines `y y of Fig. l. Fig. al is a sectional view taken on the lines z .z of Fig. l. Fig. 5 is a sectional view of the rear mole, taken on the lines l l thereon, and Fig. 6 is a view of the longitudinal division-plate removed.

Referring by letter to the said drawings, A indicates the cutter-shoe, which is so formed, with its forward end tapering, as to serve the additional function of the advance mole. Se cured to the upper side of this shoe and at a proper point, and risingl vertically therefrom, is the cutter-standard B, the form of whichis better shown in cross-sectional view, Fig. 3, having its front vertical edge forming the cutter. This shoe has its rear or enlarged end recessed, as shown at u, to receive the forward and reduced and beveled end of the rear mole, C.

pin b is placed in position and the two parts securelybut flexibly connected. By this man ner of connection it will be seen that the rear mole is practically a continuation ot' the first mole or cutter, but is allowed to move hori zontally with relation to the other, so as to avoid contact with stones or other obstructions in thc soil.

From the forward reduced end of the rear mole rises in a fixed position a second cutter, E,which is in the saine longitudinal plane as the front cutter, B, so as to travel. directly after the same. These two cutters B and E are of equal height and support a horizontal platform, F, for the operator. In the rear of the cutter-standard E is a vertical tube, G, for the delivery of cement to the mole and the trench or ditch formed thereby. This tube G I have shown as formed entire with the rear cutter-standard, although theyT may be made separately, and the said tube is provided at its upper end with a hopper, (1.,into which the cement is placed preparatory to its entrance into the tube G. This tube connects the hopper with the rear mole by means of an opening therein, as shown at e, so that the cement as it is fed from said hopper through the tube will enter the mole, which is hollow. This rear mole is made in two longitudinal sections, which are hollow, and in uniting have a metallic plate, H, interposed between them. `These two parts are connected at front by the pin which makes the connection with the front mole or shoe, and the rear ends of the sections are provided with perforated lugs f, through which a key is passed for connecting them, as shown. Thus it will be seen that the rear mole divided into an upper and a lower compartment, and it will also be seen that this mole above the horizontal partition, which has its longitudinal edges eX- tended laterally, is provided with longitudinal slots I, forming openings for the outward passage of the cement from the mole. Vithin the hopper of the cement-tube I arrange an auger, J, which is provided with a crankhandle for the operator to turn, and secured to this auger is a rod, K, which passes down through the tube G and is cranked within the mole, as shown at L, with its lower end bear ing in the bottom of the said mole or the lower end of the rear cutter-standard.

ICO

M indicates an agitator comprising a horizontal rod connected at its forward end to the cranked portion of the rod K, so that when this rod has been rotated by means of the crank this agitator will be given a rectilinear reciprocation. This agitator-rod M is threaded externally so as to receive blades or arms N screwed thereon. Thus it will be seen that when the crank-arm has been turned y the auger will feed the cement into the tube from the hopper, while the agitator will keep the discharge end of the tube from clogging, as well as the discharge-openin gs of the mole.

As before described, the forward portion of the rear mole is reduced or tapered, and the upper section thereof is grooved transverse externally in a somewhat conical form, as shown at g g. As the longitudinal divisionplate has its edges extended, it will be seen that as the cement passes out through the openings of the mole it will be checked from going' beneath it by means of the said projecting edges; therefore it will rise to the roof and upper sides of the ditch, and when draft has been applied to the apparatus the rear enlarged portion of the mole will press and smooth the cement against the soil or earth, so as to prevent the same from crumbling and falling into the trench thus formed.

An apparatus of this character may be cheaply constructed, and the driver of the draft-anim al may also attend to thc operation of the entire machine, it simply requiring a person to manipulate the crank-handle to turn the auger and reciprocate the agitator.

To permit the cement to iiow from the mole, I provide its rear end with a vent-hole, as shown at Z, and to prevent this vent-hole from clogging I provide a clearing-rod, m, which connects with the agitator, as more fully shown in Fig. 2 of the drawings.

Having described my invention, what I claim isl. The combination, with the front and rear moles connected as described, of the front and rear vertical cutters, the platform mounted thereon, the feed-tube eonnnunicating to the rear mole with the hopper thereon, and the auger therein, and the crank-shaft and agitator, all adapted to operate substantially as specified.

2. A mole formed in two longitudinal sections, thc upper one of which has its forward end tapered and its outer side grooved transversely, and also recessed to form outlet-aper tures, and a plate interposed between the two sect-ions and extended laterally, substantially as specified.

3. The combination, with a mole, of a feedtube, a rotative shaft therein, and an agitator in the mole and connected with the rotative rod, whereby a reciprocation may be imparted thereto, substantially as specified.

4. The combination, with the mole having' a vent-aperture in its rear end, of the agitator, and a clearingrod secu red to the agitator and passing through the vent-aperture, substantially as described.

5. The combination, with the mole, of the vertical feed-tube having a hopper, the rotative rod therein, the auger secured to the rod, an d the agitator connected with the lower cranked end of 'the said rod, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses. 4
